Which statement is a true statement about isosceles right triangle?
That it has a 90 degree angle and two equal 45 degree angles
Why does a catapult shoot best from a 45 degree angle?
The [horizontal] range of a projectile is maximised when it shoots at a 45 degree angle. This is true if air resistance is ignored so that the only force acting on the projectile is gravity.
A certain triangle has a 30 angle and 60 angle which must be a true statement about the triangle?
The longest side is twice as long as the shortest side.
True or false The slope is equal to the angle of a line?
true or false ? perpendicular lines intersect at an angle of 45
Is this True or false the angle bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the base?
True
Is the critical angle the same thing as the angle of incidence?
The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection. It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.
When a wave is reflected the angle of reflection of incidence true or false?
True. The angle of reflection is equal to the angle of incidence when a wave is reflected off a surface. This is known as the law of reflection.
True or false- the angle of incidence is always greater than the reflection angle?
False .According to laws of reflection, the angle of incidence is always equal to the angle of reflection.
When a light ray is reflected by a mirror is the angle of the light ray and the reflected ray different or the same?
Angle of Incidence = Angle of ReflectionThis is only true if the angle of incidence is greaterthan the critical angle.
Is the angle between the incident ray and the plane mirror is the complement of the angle of incidence true or false?
true or false
Could a 10 degree angle be congruent to a 10 degree angle?
is true a 10 angle is cngruent to a 10 angle
What is you say about the relationship between the angle of the incidents and Angle of reflection?
The angle of incidence is always equal to the angle of reflection. This relationship is known as the law of reflection, which holds true for all types of surfaces, whether they are smooth or rough.
Is it true that a 25 degree angle is congruent to a 25 degree angle?
Yes. It is so true that if they are side-by-side, you can hardly tell them apart.
Does a right angled triangle have a 90 degree angle?
Yes, the definition of a right triangle is that it has a 90 degree angle
An angle has two edges is 60 degree in angle plats true or false with a common endpoint true or false?
Yes, it is true that angle 60 degrees has two edges in the angle parts.
What is true about the angle of incidence and the angle of reflection for curved mirrors?
Those angles are equal at the point where a ray of light hits the mirror,regardless of the shape of the mirror.
How According to the law of reflection the angle of incidence is the angle of reflection?
According to the law of reflection, the angle of incidence (the angle between the incident ray and the normal to the surface) is equal to the angle of reflection (the angle between the reflected ray and the normal to the surface) when a ray of light reflects off a surface. This principle holds true for any surface, creating consistent patterns of reflection.
